ELECTRIC SHAVING MACHINE.

Application filed January 7, 1924. Serial No. 684,866.

pliances and the primary object of the invention is to provide a power driven machine for both applying and working a lather up on the face and for shaving the face.

Another prime object of the invention is the provision of a supporting handle carrying a rotatable drum and novel means for driving the drum, the drum having associated therewith suitable cutting blades and guards, whereby the beard can be quickly and readily removed by holding the drum in close proximity to the face.

A further prime object of the invention is the provision of novel means for forming the drum and the blades, whereby the blades can be readily removed from or associated with the drum when so desired.

A further object of the invention is the provision of novel guard comb members carried by the drum for receiving and support ing the blades, whereby the blades will b held in an operative position relative to the faced during the shaving operation.

A further object of the invention is the provision of novel guard plates for holding the blades on the combs and novel means for moving the plates to an inoperative position to facilitate the cleaning of the blades.

A further object of the invention is the provision of novel means for detachably mounting the drum upon the holder, so as to permit the disassembling of the device when necessary.

A still further object of the invention is the provision of novel means for associating a shaving brush with the drive shaft for the drum, whereby the brush can be rotated for facilitating the applying and working up of the lather onthe face.

A still further object of the invention is to provide a novel shaving appliance of the above character, which will be durable and eificient in use, one that will be simple and easy to manufacture and one which can be placedupon the market at a reasonable cost.

with these and other objects in view, the

invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described. claimed and illustrated in the accompanying drawings, in which drawings:

Figure 1 is an enlarged longitudinal section through the improved shaving appliance illustrating the means for mounting the drum in position on the holder.

Figure 2 is an edge elevation of the improved shaving appliance.

Figure 5 is an enlarged fragmentary plan view of the drum showing the combs and guard plates associated therewith, and

Figure 6 is an enlarged fragmentary side elevation of the drum showing parts thereof in section, illustrating the blade, guard and combs and plates in position thereon.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indicates the improved shaving appliance which comprises a U-shaped holder 10 including arms 11 and. a shank portion 12, which can have associated therewith any preferred type of hand grip 13. The U-shaped holder 10 has connected therewith between the arms 11 a suitable cup 14: for the reception of lather and the like, as the same is shaved from off of the face. The shank 12 is of a hollow construction and is provided with suitable bearings 15 for the reception of. a drive shaft 16 which can be operated in any desired way from any preferred type of elec tric motor (not shown). This motor (not shown) can be contained in the handle or at a point distant from the handle. In case the shaft 16 is driven by a motor at a point distant from the handle, a flexible shaft 17 is connected to the outer end thereof as shown in Figure 1 of the drawing. One arm 11 is rovided with a gear housing 18 into which protrudes one end of a flexible shaft 19 which is connected with a drive shaft 16. The end of the flexible shaft 19 which extends into the gear housing 18 is rovided with a beveled gear 20 which mes es with a beveled gear 21 keyed or otherwise secured to a supportin shaft 22. This supporting shaft 22 exten outu I wardly of the yoke 10 carries plate is adapted to hold its blade 'tend and gear casing 18 as clearly shown in Figure 1 of the drawing, and is provided with a socket of polygonal configuration, for a punpose, which will be hereinafter more fully described. The beveled p nion 21 carries a screw-threaded sleeve 24' for receiving ,the threaded end of a shank 25 carried by the shavng brush 26. Thus it can be seen that the shaving brush 26 is also op rated by the beveled pinion 21.

The opposite arm 11 of the U-shaped a sliding-supporting pin 27 for engaging oneend of the drum 28, the oppos'te end of which carries a pin 29 for engaging in the socket 23 of the shaft 22. The pin 27 is normally held in engagement with the drum 28 by the use of an expansion spring 30 which is coiled about the pin and which has one end in engagement therewith and one end in engagement with the last metioned arm 11 of the yoke 10. This pin 27 is provided with a thumb piece 31, whereby the pin can be slid against the tension of the spring 30 out of engagement with the drum 28. J

The drum 28 is of a solid construction and has extending longitudinally across the .same in spaced relation to the periphery thereof at equidistant spaced points the combs 32 which act as rests for the active ends of the razor blades, which will be hereinafter more fully described. The guard combs 32 are formed integral withan annular flange 33 formed on one end of the drum 28 and the ends of the combs which are remote from the flange 33 are provided with hearing lugs 34, for a purpose, which will be hereinafter more specifically described.

The razor blades 35 correspond in number to the combs 32 and these blades are struck out from a cylindrical metal sleeve 36, which is adapted to be received on the drum 28. After the metal sleeve 36 is placed on the drum wth one edge thereof in contact with the flange 33, the sleeve is rotated, so as to position the blades 35 over the combs 32 as clearly shown. in Figure 6 of the drawings. An arcuate guard plate 37 is provided for each blade 35 and this guard in intimate contact with the guard comb 32. These guard plates gradually decrease in width toward their forward ends and have their rear ends rounded and provided with pivot pins 38 and 39. The pivot pins 38 exthrough suitable bearing openings formed in the flange 28, while the pins39 extend into the pivot lugs 34 supported by the combs 32.

In order to hold the metal sleeve 36 in position on the drum against lateral movement to provide means for operating the guard plates 37 and for holding the same in intimate contact with the blades 35, a relatively 39 and secured thereto in any desired way.

Now it is obvious that by turning the gear 40 in one way or the other, that the guard plates 37 can be raised or lowered.

From the foregoing description, it can be seen that I have provided an improved shaving machine embodying a power driven razor blade carrying cylinder and a shaving brush.

Changes in details may be made without departing from the spirit or the scope of this invention.

What I claim as new is:
